· JVASP-21968· Li3AlN2

Li₃AlN₂ is a ternary nitride ceramic compound combining lithium, aluminum, and nitrogen, belonging to the family of advanced ceramic materials with potential for high-temperature and electrochemical applications. This material remains largely in the research and development stage, where it is being investigated for solid-state electrolyte systems in next-generation lithium-ion batteries and as a component in composite ceramics due to its ionic conductivity and thermal stability. Engineers consider nitride ceramics like Li₃AlN₂ when conventional oxide electrolytes or polymeric separators cannot meet performance requirements in high-energy-density battery systems or when extreme thermal environments demand chemically inert, lightweight ceramic phases.
